Horizontal shareholdings exist when a common set of investors own significant shares in corporations that are horizontal competitors in a product market. Economic models show that substantial horizontal shareholdings are likely to anticompetitively raise prices when the owned businesses compete...

Although empirical studies show that common shareholding affects corporate conduct and that common horizontal shareholding lessens competition, critics have argued that the law should not take any action until we have clearer proof on the causal mechanisms. I show that we actually have ample...

Horizontal shareholding exists when significant shareholders have stock in horizontal competitors. (It is often imprecisely called "common shareholding," but that term can also apply when shareholders own stock in two noncompeting corporations. It differs from "cross-shareholding," which...

This Article shows that new economic proofs and empirical evidence provide powerful confirmation that, even when horizontal shareholders individually have minority stakes, horizontal shareholding in concentrated markets often has anticompetitive effects. The new economic proofs show that,...

Using a unique data set, I study how stock markets react to positive and negative events concerned with a firm's corporate social responsibility (CSR). I show that investors respond strongly negatively to negative events and weakly negatively to positive events. I then show that investors do...

General equilibrium models of oligopolistic competition give rise to relative prices only without determining the price level. It is well known that the choice of a numeraire or, more generally, of a normalization rule converting relative prices into absolute prices entails drastic consequences...

CEO compensation is increasingly being linked to ESG outcomes. In this paper, we provide evidence that ESG targets in CEO pay reflect stakeholder welfare. Using granular information on contract design from Swedish firms, we show that ESG-linked contracts are more likely for CEOs with broader...

Shareholders want a firm's objective function to place some weight on consumer welfare, motivated by both self-interested and altruistic motivations. Firms have a unique technology for improving consumer welfare: lowering inefficient price markups, which increases consumer welfare more than it...

We study the impact of accelerated vesting of equity awards on takeovers, whereby the restricted stock and/or stock options of the target CEO immediately vest and become unrestricted upon the close of the acquisition. We find that takeover premiums are significantly larger when the target CEO...
